Graphics

If you startx at this point, you may not have a working keyboard or touchpad. Installing the keyboard and synaptics drivers should fix that.

pacman -S xf86-input-keyboard xf86-input-synaptics

If you want to use an external mouse, you may also need

pacman -S xf86-input-mouse

While you can run a full desktop environment like KDE or GNOME, it will be a little sluggish on the S10. If you only have 512 MB of RAM, you will use it up quickly. Xfce runs with more acceptable speed. LXDE (or just Openbox) feels even more responsive. Lighter is definitely better on this machine, especially if you have not installed more RAM.

Sound

Works out of the box but the internal microphone is not turned on by default. To make the internal microphone work, turn the capture channel on (using the spacebar in alsamixer if you are using that), unmute the internal microphone channel and turn it up.
